IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 207,142, dated August 20, 1878; application filed February 26, 1878.

To all whom it may concern:

Be it known that I, .THoMAs B. TUFTs, of Le Roy, in the county of Genesee and State vof New York, have invented a certain new and useful Improvement in (looking-Stoves; and I do hereby declare that the following is a full, clear, and eX'act description ofthe construction and operation of the same, reference being had to the accompanying drawings, in which- Figure 1 is a central vertical section of my improved stove. Fig. 2 is a section at right angles to that in Fig. 1, and showing the tirepot and grate in elevation. Fig. 3 is a perspective view of a portion of the front plate of the tire-pot and grate.

My improvement relates to the specialconstruction and arrangement of the lire-pot and grate, as hereinafter more fully described and definitely claimed.

A represents a cooking-stove of ordinary form and construction. B is the lire-pot.

It will beobserved that the back plate, b, and end plates, c, form the sides and ends, and the longitudinally-curved portion d forms the front, of the re-pot, the whole being of an oblong or approximately-reetangular shape in horizontal section. The top of the tire-pot en' tirely or nearly fills the whole area of the front chamber of the stove, while the bottom is narrower, thereby leaving a dead-air space, a a, all around it. The fire-pot is therefore of somewhat conica-l form, standing centrally in the stove-chamber.

The back b and ends c c of the fire-pot extend down full width to the bottom, and are formed in one continuous body, and at the extreme bottom is located the ordinary iiat dumping-grate C, which is inclosed by said back and ends of the iire-pot.

The front plate,'d, of the {ire-pot is narrower, extending but part way down, and at the bottom of this are gratings or legs f j', some inches in length, standing vertically, but leaving an open space, g, between their lower ends and the top of the grate C. These grat ings are fargenough apart to allow the entrance of a poker. The grate is mounted on an axis, 7L, by which it may be dumped.

By the construction above described the body of coal is perfectly inclosed on the back and ends, below the grate, and in front it is inclosed, except through the space g and the gratings ff, which allow suflicient draft, and a particular advantage is, that a poker may be inserted through the gratings ff, and ashes and clinkers can be drawn out through the space g without shaking the grate or disturbing the lire; and in case of large clinkers, if the space g is not suflicient for them to pass, the grate can be inclined slightly downward without dumping the fire, and such clinkers can be readily. removed.

The back and end plates, b c c, by extendingv below the front plate, d, and by standing in the inclined position before described, serve as chutes to throw the ashes and clinkers forward over the grate, and to facilitate their discharge through the opening over the grate, thereby makin g the nre-pot more effective than when made in the ordinary form. These projecting end plates also enable the journals of the gra-te to be hung therein, obviating the necessity of a cross-bar or other attachment beneath the fire-pot to secure the grate.

I am aware that grated fronts to fire-pots extending up the whole front are well known.

I am also aware that a heating-stove has been provided with an annular fire-pot narrowing toward the bottom, and the rear part projecting 4,below the front portion, said firepot being provided with a circular and tilting grate, and such I hereby disclaim 5 but The combination, with the front chamber of a cookin g-stove, of the longitudinal inclined back and transverse end plates, b c, and curved front plate, d, the whole forming a iire -pot approximately rectangular in horizontal section, each of the said back and end plates projecting below the front plate, and the end plates having bearing below the front plate to support a dumping-grate, all substantially as and for the purpose described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

THOS. B. TUFTS.
